Open Innovation via Java-enabled Network Devices Tal Lavian

Collaboration with Business Applications New paradigm of distributed applications Network devices collaborating with business applications Application aware routing JVM Oracle DB E-Commerce Business apps SAP, ERP, Optivity RMI, XML, CORBA Apps Switch Router Net-Device JVM Apps Apps Server Oplet

Server Collaboration Supports distributed computing applications in which network devices participate –router to router –server to router Supports Intelligent Agents Supports Mobile Agents Java-based Application Java-based Application Java-based Application

Active Network Management Download Oplet Service to the device. Monitor MIB variables Might be complex conditions Trend analysis DiffServ, RMON-II, etc… MIBs Report “events” to NMS –drop rate, packets/second Allow Service to take action Download application Adjust parameters based on direction from NMS Monitor Appropriate Application Download Complex Condition Exceeded NMS No more polling router Extensive access to internal resources

Diagnostic Mobile Agents Automatic trace-route from edge router where problem exists. –Each node reached generates a report to NMS –Trace-route code “moves” to next node in path –Mobile agents identify router health –Create logs for NMS

Active Intrusion Detection Intruder is identified by Intrusion Detection software Intruder signature is identified Mobile agent is dispatched in direction of intruder (based on physical port of entry) Mobile agent “chases” intruder and terminates him (shuts down link, reboot host, notify NMS)
